Valve-controlled connector for air-conduits.



FRANK B. CHBROIN, 0F SEATTLE, WASHINGTON.

To @ZZ ivkom t may concern: Be it known that I, FRANK B. CHARROIN,

. citizen of the United States, residing -at Seattle, in the county'of King and VState of Washington, have invented a certain new and useful Improvement in Valve-Controlled `Connectors for Air-Conduits, of which the following is a specification.

My invention relates toimprovements in connectors for making temporary connections between lex'ible conductors of -compressed. air and check-valve controlled pas,-

sageways leading into receptacles that areV to becharged with. such-compressed air'; and

Ithe object of my improvement is to provide a connector which may be'attached to one end of a hose whose ,other end is connected with a source of compressed air, and which p shall embody a valve that shall be actuated to open the passageway through it when its outlet end is pressed intoengagement with a suitable nipple that forms the inlet passageway of a pneumatic ltire of a vehicle or.

j other Ireceptacle to be charged with compressed air, said valve being adapted to close automatically upon disengagement from said nipple. i f

I accomplish this object by devlces illustrated in the accompanying drawings i f of the annular face of the outlet end of said valve-case 4.

wherein-- Figure 1 isla view in vertical mid-section of a` connector embodying my invention;4

Fig. 2 isan enlarged perspective view of a detail V ofthe same; and -Fi 3 is a' frag-4 mentary view in vertical mi -section of the same, showing vpositions of Aoperative Vparts when the connector is in engagement withi a llippleformingJ a passageway'toa receptacle' (not shown) to pressed air.-

Referring to be charged with comwhich -like referencel numerals indicate like parts, a valve-case-4 is provided with an inf movable internally screw-threaded clampangle with' respect to the axis-thereof to adapt it to be attached to an end of a flexi.- l

ble hose and further provided with a .re-

ing collar 6 disposed on its outlet endto clamp a disk 7 of ,flexible material, as-of `soft vulcanized rubber, to the outer annular sur- I t face of the outlet endv of thecircular wall of saidvalve-case 4j said Adisk 7 being pro- A vided with a concentrically. disposed .orifice 8 throu h which a jet-of compressedair may pass. r ithinthe valveLcase 4 -is disposed a.-I

valvefspindlel 9 whose lower end is providedwith an""integral disk-like valve member 10 whose bottom face is provided with a centrally disposed recess 1l and with a concentrically disposed annular recess 12 which bottom face is normally maintained m engagement with' the inner side surface of the flexible disk 7 by means of a helical compression spring 13 which surrounds the spindle 9 to extend from the disk-like valve member 10 to a shoulder formed on the interior surface of the valve-case 4. The form of the valvefspindle 9 and the disk-like valve member 10 is more clearly shown by perspective view in Fig. 2.

, The valve member 10 is provided with a plurality of 4holes 14 which extend through the wall which separates the recesses 11 and 12 whereby air may flow from the recess 12 to the recess 11 to gain access to the orifice 8 in the flexible disk 7. The valve-spindle 9 and the disk-like valve member 10 are ofI .'tween the outer edge portion of the disk-like valve member 10 andthe inner edge portion The hole 16 through the collar 6 is of such diameter as will adapt it to permit the insertien of anipple, as the nipple 15 shown in Fig. 3, whieh nipple 15 may represent a nipple forming a part of a check-controlled passageway leading into a pneumatic tire,

and the thickness of the metal between the disk 7 and the outer face of said collar 6 is such that the hole 16 will be'a length that will adapt it to guide said nipple 15 as such nipple 15 is inserted within said hole 16, to cause its end surface to be seated in `even engagement with the outer surface of the exible disk 7.4

rlhe` operation of my connector may be described as follows: The nipple 5 is inserted in one end of a flexible hose and securely ,lamped therein by suitable binding means, the other end of said hose being connected with a source of supply of compressedair whereupon such compressed air, with the aid of the helical spring 13,v will orifice 8 by reason of the outer annular surface of the lower face of the disk-like valve member 10 being in engagement with the inner fiat surface of the flexible disk 7, then the connector is forced on to the end of the check-valve controlled nipple, as the nipple 15, of a pneumatic tire which is to be inflated, whereby the end surfaces of said nipple, as the nipple 15, will press the flexible disk 7 to bulge inwardly thus pressing inwardly the disk-like valve membe'r 10 against the force of the helical spring 13 and the pressure of compressed air to the position shown in Fig. 3, thus to cause the outer annular portion of the adjacent outer face of the disk-like valve member 10 to disengage from its cont-act with the inner surface of the flexible disk 7 while the inner annular portion of said adjacent outer face of said disklike valve member 10 will be caused to engage with said disk 7; and with the operative parts in such relative positions compressed air may pass from the nipple 5 into the interior of the valvecase 4, thence through the space between the periphery of the valve member 10 and the wall of the valve-case 4 into the annular recess 12, thence through the holes 14 into the recess 11, thence through the oriice 8 into the passageway through the nipple 15, thence through the check-valve (not shown) therein to the yspace within the pneumatic tire to be inflated and when such tire is sufficiently inflated the connector is detached from the nipple, as nipple 15, where upon the iiexible disk 7 will reassume its position in a flat plane, as shown in Fig. 1, whereby the outer annular portion of the outer face of the disk-like valve member 10 will again engage with the inner surface of the disk 7 to prevent in an obvious manner air from gaining access to the orifice 8 through the annular recess 12 and holes 14.

Manifestly, changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

What I claim is:

1. In a hose coupling, a casing formed with a chambered recess having cylindrical .side walls and a tubular nipple communicating with said recess; a cap secured over said -casing to inclose said recess, said cap being provided with an opening axially of said recess; a diskof flexible material se cured between said casing and said cap, said disk being provided with a concenn trically disposed orifice extending therethrough, a valve member disposed within said recess, said valve member being of a smaller diameter and of shorter lengthk than said recess, and being provided with an annular recess and a concentrically disposed recess in one of its end surfaces adjacent to the inner side of said disk to provide two concentrically disposed walls, the face of the outer wall projecting beyond the plane of the face of the inner wall whereby only said outer wall may engage with said disk when said disk is in its normal shape and whereby only said inner wall may engage with said disk when said disk is pressed inwardly to form a concavo-convex shape; and a passageway for air disposed to eX- tend through said inner annular wall.

2. In a hose coupling, a casingformed with a chambered recess having cylindrical side walls and a tubular nipple communim cating therewith, a cap secured over said casing inclosing said recess and provided with an opening axially of said recess, a gasket secured between said casing and said cap having an opening in the axis of said recess, v'and a valve member arranged for limiting longitudinal movement within said recess, said valve member being of smaller diameter than said recess, to afford a passageway for air, and being chambered on its underside to provide a circular edge engageable with said gasket, the said gasket arranged to be engaged and moved to concavo-convex position to unseat` the valve.

8. In a hose coupling, a casing formed with a chambered recess having cylindrical side walls and a tubular nipple communicating therewith, a cap secured over said `casing inclosing said recess provided with an opening axially of said recess, a gasket secured between said casing and said cap having an opening in the axis of said recess, and a valve member arranged for limited longitudinal movement within said recess provided with means upon its upper side to prevent the closing of thel passage into said nipple, said valve member being of smaller diameter than said recess to afford a passageway for air and being chambered on its underside to provide a circular edge engageable with said gasket, the said gasket arranged to be engaged and moved to concavo-convex position to unseat the valve.

In witness whereof, I hereunto subscribe my name this 19th day of May, A. D. 1915.
